Re: [Xen-users] Problem with dom0_mem=6144M
I have always used syntax
dom0_mem=6144000
And that works for me.
I have never tried to use the M and not sure what it would do.
The default units are KB. the only thing that I have seen
that gives you less memory in dom0 than what you expected is if
you make too many domU's and xen takes the memory out of dom0's hide.

Hi all,
I try to set dom0_mem=6144M in my xen 4.0.2-rc1-pre with pv_ops kernel
2.6.32.24 (jeremy source) but after boot my dom0 appear in "free -m" 5408M.
My logs:
# xm info|grep memory
total_memory : 32755
free_memory : 27658
My free -m:
# free -m
total used free shared buffers cached
Mem: 5408 2060 3347 0 17 133
In my menu.lst:
title KERNEL-XEN
root(hd0,0)
kernel /xen.gz dom0_mem=6144M
module /vmlinuz-2.6.32.24 ro nomodeset root=/dev/VolGroup00/LogVol00
module /initrd-2.6.32.24.img
In compilation I set this:
CONFIG_XEN_MAX_DOMAIN_MEMORY=128
Could anyone help me? Anyone experienced this?
Thank you for any help.
